Description

Genuine Ataxioceras elmii Ammonite Fossil

This listing is for a genuine Ataxioceras elmii ammonite fossil from Titting, Bavaria, Germany. Dating from the Lower Kimmeridgian Stage of the Upper Jurassic, this specimen represents a collectible European Jurassic ammonite from the classic fossil-bearing marine deposits of southern Germany.

Ataxioceras elmii is a desirable ammonite for collectors who appreciate named species, strong geological provenance, and attractive ribbed shell forms. This fossil is a carefully chosen piece, and the photograph shows the actual specimen you will receive. Full sizing can be seen in the photo.

Geology, Age and German Locality

This ammonite comes from Titting, in Bavaria, Germany, an area associated with the fossil-rich Jurassic rocks of southern Germany. Bavaria is well known for its Upper Jurassic marine deposits, including limestones and associated sedimentary beds that preserve ammonites, belemnites, bivalves, brachiopods, echinoids, fish remains, and other fossils from ancient European seas.

The fossil is Lower Kimmeridgian in age, placing it within the early part of the Kimmeridgian Stage of the Upper Jurassic, approximately 157 to 155 million years old. The Kimmeridgian was an important interval in ammonite evolution, with many perisphinctid ammonites developing diverse shell forms and ribbing patterns. Ammonites from this stage are especially important in palaeontology because they are widely used for dating and correlating Jurassic marine rocks.

During the Late Jurassic, the region now known as Bavaria was covered by warm marine waters connected to wider European shelf seas. Sediments accumulated across the sea floor, preserving the remains of marine animals that lived in the water column and on the seabed. Fossils from this region are highly regarded because southern Germany has a long history of Jurassic fossil study and collection.

Fossil Type and Species Details

Ataxioceras elmii was an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Like other ammonites, it possessed a coiled external shell divided internally into chambers. The living animal occupied the final body chamber, while the earlier chambers helped regulate buoyancy as it moved through the Jurassic sea.

The genus Ataxioceras is part of the diverse Upper Jurassic ammonite faunas of Europe and is especially associated with Kimmeridgian marine strata. Ataxioceras ammonites commonly show planispiral coiling, rounded to moderately compressed whorls, and strong ribbed ornament. Depending on growth stage and preservation, the ribs may appear dense, branching, curved, or interrupted across the whorl, giving the shell a distinctive textured appearance.

Scientific classification places Ataxioceras within Phylum Mollusca, Class Cephalopoda, Subclass Ammonoidea, Order Ammonitida, Superfamily Perisphinctoidea, and Family Ataxioceratidae. This group of ammonites is closely linked with Upper Jurassic biostratigraphy, where shell shape, ribbing, and whorl development are important features for identification.

Lower Kimmeridgian Marine Environment

During the Lower Kimmeridgian, southern Germany formed part of a broad marine shelf environment. Warm Jurassic seas covered the area, creating ideal conditions for ammonites and many other marine organisms. These waters supported a varied ecosystem of belemnites, bivalves, brachiopods, gastropods, echinoids, crustaceans, fish, sharks, and marine reptiles.

Ataxioceras elmii would have lived within this ancient sea as part of the active cephalopod fauna. Its chambered shell allowed buoyancy control, helping the animal move through the water column while feeding and avoiding predators. Ammonites were important members of Jurassic marine food webs and are among the most iconic fossils from the Mesozoic Era.

The fossil-bearing deposits around Titting preserve evidence of these ancient marine conditions. Specimens from this area are particularly appealing to collectors who value European Jurassic fossils with accurate locality information and a clearly stated geological age.

Collectible Upper Jurassic Ammonite

This Ataxioceras elmii ammonite fossil is an excellent specimen for collectors of German fossils, European ammonites, Upper Jurassic fossils, Kimmeridgian ammonites, and scientifically labelled natural history specimens. Its named species, Lower Kimmeridgian age, Bavarian locality, and classic ribbed ammonite form give it strong display and educational appeal.
